Gnee Steel is a leading manufacturer, supplier, and exporter of high-quality Inconel 718 plates, sheets, and coils in China. Our Inconel 718 plates and sheets are aluminum-added nickel-chromium alloys with excellent oxidation resistance and high-temperature corrosion resistance. These products (including UNS N07718) are widely used in various fields, such as heat treatment furnaces, catalyst support grids in nitric acid production, radiant tubes, and steam superheater tube supports.
Comprehensive Explanation of Inconel 718 Alloy Plate
Comprehensive Explanation of Inconel 718 Alloy Plate
Inconel 718 sheet (UNS N07718) is a precipitation-hardening nickel-chromium-based superalloy widely considered the material of choice for high-strength, high-temperature applications. Developed in the 1960s, this alloy now accounts for nearly 50% of total nickel-based superalloy production. Its unique combination of properties includes excellent corrosion resistance, superior creep rupture strength at temperatures up to 700°C (1300°F), and good weldability. Inconel 718 sheet metal is a common material in the aerospace, oil and gas, and shipbuilding industries.
What are the characteristics of Inconel 718?
Inconel 718 alloy (UNS number N07718) is one of the most commonly used nickel-based superalloys. These alloys are characterized by high strength, excellent high-temperature resistance, corrosion resistance, and oxidation resistance. IN718 is specifically designed to maintain fatigue and creep resistance at temperatures up to 700°C.
